Behavioral assessment of shelter dogs determines their adoptability and fate. Improving assessment validity reduces unjustified euthanasia and improves matching between dogs and adopters.
Shelter behavioral assessment directly determines life and death for hundreds of thousands of dogs annually. The welfare stakes of assessment validity are therefore enormous. Traditional bite-risk assessments administered in the artificial, stressful shelter environment frequently produce false positive results — dogs appearing dangerously aggressive who would behave normally in a home. The shelter-stress artifact means that many dogs euthanized for behavioral reasons in shelters would have been adoptable companions in different assessment conditions. Evidence-based reforms including extended observation periods, foster-based assessment, and post-adoption follow-up to track actual behavior dramatically improve assessment accuracy and reduce unjustified euthanasia.
